Re: [mythtv-users] LiveTV & MythMusic - Just lost sound

Tue, 10 Jan 2006 11:12:22 -0800

In addition to the optical audio cable I was using I added an analog audio cable between my MythTV box and my receiver.  Now when I use live TV or MythMusic I just have to push the button on my receiver to switch from digital audio to analog audio.  It works now, but I don't understand why it worked at first with just the optical cable.

Could it have something to do with this line in my modprobe.conf?

I'm running MythTV 0.18.1 with a PVR-250.  I'm using the motherboard's via82xx audio chipset with spdif out to my receiver.  I just built the MythTV box today and everything was working fine.  I'm using Xine for MythVideo and MythDVD.  Both of those play audio and video just fine.  However, after about and hour of use LiveTV and MythMusic just stopped playing audio for no apparent reason.  I double-checked the audio settings in the setup menu.  I think these are right:
 
Audio output device = /dev/dsp
enable ac3 to spdif passthrough = unchecked
mixer device=/dev/mixer
mixer controls = pcm
 
I did notice one thing that changed, but I don't know how it happened and unfortunately changing it back didn't fix the problem.  On this sound card there is a slider in alsamixer labeled "IEC958 Playback AC97-SPSA" that needs to be at zero to enable spdif output.  I had set it to zero previously, but some how it was set to 100%.  I turned it back down, but still no audio from LiveTV or MythMusic.  MythVideo and MythDVD through Xine still work just fine.  I tryed playing a file with aplay and there was no sound with it either.  My asound and modprobe.conf files are below.  I don't know what else to check.  Has anyone seen this before?
